RANGE STATEMENT
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts.
Where reference is made to industry codes of practice, and/or Australian/international standards, the latest version must be used.
Context
This competency applies to operators demonstrating some relevant theoretical knowledge and using a range of well developed skills requiring some discretion and judgement.
Procedures
All operations are performed in accordance with procedures.
Procedures means all relevant workplace procedures, work instructions, temporary instructions and relevant industry and government codes and standards.
Tools and equipment
This competency includes use of equipment and tools such as:
extruder
die, air ring and blower
bubble guides and rollers
film rollers, slitting, trimming and winding gear
coolers, heaters and ancillary equipment
hand tools, knives, adjustment tools
relevant personal protective equipment.
Hazards
Typical hazards include:
high air velocities
high voltage corona treatment systems sharp knives
high towers manual handling
fumes, humidity, air temperatures, radiant heat, hot dies stationary and moving machinery, parts and components.
Problems
'Anticipate and solve problems' means resolve a wide range of routine and non-routine problems, using product and process knowledge to develop solutions to problems which do not have a known solution/a solution recorded in the procedures.
Typical process and product problems may include:
extruder control, temperature, pressures, screw speed contamination
bubble control, size, stability
blemishes, voids, gels, die and weld lines, burn marks, poor surface finish, poor colour dispersion, partially decomposed products, uneven colour, contamination of colour
alignment and control of trimming and winding gear
materials variations
worn/damaged dies and extruder adjustments
raw material contamination, wrong grade, variations of polymer properties
hydraulic pressure variations, temperature variations, loss of power or drives
process sequencing problems
variations in component speeds.
Variables
Key variables to be monitored include:
extruder operating temperatures, melt temperatures, back pressures and current (amps)
nip and winding speeds, nip roller settings
corona treatment settings
winder settings, slitters, trimmers and die gap adjustments
colour
output rate
product thickness
product integrity and general conformance to specification/sample.

The Evidence Guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for this Training Package.
Overviewof assessment
Assessment will occur on an industrial blown film machine(s) equipment and will be undertaken in a work-like environment.
Where the assessee does not currently possess evidence of competency in PMBPROD216A Operate blown film equipment, it may be co-assessed with this unit.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
It is essential that competence is demonstrated in the knowledge and skills defined in this unit. These may include the ability to:
identify critical materials properties and blown film process characteristics in relation to the process requirements and the end product.
Consistent performance should be demonstrated. For example, look to see that
production quality and output standards are met consistently
the process runs consistently and smoothly.
Assessment method and context
Assessment will occur on an industrial blown film machine(s) equipment and will be undertaken in a work-like environment.
Competence in this unit may be assessed
by using an appropriate, industrial blown film equipment
in a situation allowing for the generation of evidence of the ability to respond to problems
by using a suitable simulation and/or a range of case studies/scenarios
through a combination of these techniques.
In all cases it is expected that practical assessment will be combined with targeted questioning to assess the underpinning knowledge and theoretical assessment will be combined with appropriate practical/simulation or similar assessment. Assessors need to be aware of any cultural issues that may affect responses to questions.
Assessment processes and techniques must be culturally appropriate and appropriate to the oracy, language and literacy capacity of the assessee and the work being performed.
Specific resources for assessment
This section should be read in conjunction with the Range Statement for this unit of competency. Resources required include suitable access to an operating plant or equipment that allows for appropriate and realistic simulation. A bank of case studies/scenarios and questions will also be required to the extent that they form part of the assessment method. Questioning may take place either in the workplace, or in an adjacent, quiet facility such as an office or lunchroom. No other special resources are required.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
